tech knowledge -- technology issues are not good. however, i am just telling you this, he should have communicated better. we are taking our eye off of the ball by looking at this as a problem of bob greifeld communicating. in order to price security, you have to jump through so many hurdles that are so difficult. cheryl: what he could do here, though, is upgrade the software. you have layer upon layer of software. i would think he needs to go in at this point and make that the first thing that he handles. is that the strategy? >> charlie is absolutely right. the structure of the market will continue to evolve. it will be a bumpy process. that makes communication even more important. there was evidence that mr. grunfeld was slow to inform his board. i think that is a pretty serious issue. if i am a major shareholder -- charlie: he did not brief his board -- i am not covering up for him. i am just saying, it is a real big issue. cheryl: you have been all over this story. thank you so much. i like how you two are staying friendly. char
